Named in memory of the brothers Giovanni (1901–1965) and Angelo (1911–1990) Bernasconi, renowned Italian amateur astronomers. Giovanni was a codiscoverer of comets C/1941 K1 (although his discovery was not registered because of a delay in communications in wartime Europe), C/1942 C1 and C/1948 L1. Angelo developed a method for determining the real shape and orientation of cometary tails. Both brothers were active observers of comets, meteors and variable stars. In 1965 they established in Saronno a club of amateur astronomers, now named ‘Gruppo Astrofili Giovanni e Angelo Bernasconi’. (M 30803) _ _.
